@NikCharlebois Question here. The function Get-M365DSCWorkloadsListFromResourceNames is supposed to return the workloads from given input resources. The example is as the @PsySuck describes: Get-M365DSCWorkloadsListFromResourceNames -ResourceNames AADUser. But now the caveat: Inside of the function, it's expected that the input resources contain a Name and a AuthenticationMethod property? Why is that the case? The function description doesn't contain any more information about it.

switch ($resource.Name.Substring(0, 2).ToUpper())
{
    'AA'
    {
        if (-not $workloads.Name -or -not $workloads.Name.Contains('MicrosoftGraph'))
        {
            $workloads += @{
                Name                 = 'MicrosoftGraph'
                AuthenticationMethod = $resource.AuthenticationMethod
            }
        }
    }
...
}

The call to $resource.Name.Substring(...) leads to the exception of the issue. In my opinion, this is an error and should be corrected.
